HELP I WILL GIVE BRANNIEST

Answer:

0.75s , 15ft

Step-by-step explanation:

Use Derivatives,

Notice that the above function is a quadratic curve, meaning it has either a maximum or minimum point, which is the turning point and that is what we are solving for to find a 'max' or 'min'.

\frac{d}{dt}h = \frac{d}{dt}(-16t² + 24t + 6)

\frac{dh}{dt} = -32t + 24

At turning points (max/min),

the gradient is 0 meaning,

\frac{dh}{dt} = -32t + 24 = 0.

t = 24/32 = 3/4

so time = 0.75 second

Substitute this t into the function,

we get h = -16 * 0.75 *0.75 + 24 * 0.75 + 6 = 15ft

Suppose you were able to take a large piece of paper of ordinary thickness and fold it in half 50 times. what would the height o
Lapatulllka [165]
see the attached table

the function will be

y=2<span>^n
n= number of folds
y= </span>thick (number of sheets)

the answer is 

the height of the folded paper will be 4.50 E+12 in------> 1.62 E+13 m

the result obtained exceeds all the comparisons indicated in the problem (see the attached table)
